CONCRETE-BLOCK MACHINE.

Specification of Letters Patent.

Patented Jan. 21, 1913.

Application filed June 21, 1911. Serial No. 634,464.

To all whom it may concern Be it known that we, GEORGE F. WALKER andWVALTER S. MATHES, citizens of the United States, residing at Bazine, inthe county of .Ness and State of Kansas, have invented certain new anduseful Improvements in Concrete-Block Machines, of which the followingis a specification, reference be- 3 1 represents the mam frame-work of aconing had to the accompanying drawings.

This invention relates to concrete ma chines, and more particularly to aconcrete machine for the manufacture of tile.

Objects of this invention are to provide a concrete machine which willmake the concrete tile readily and efliciently.

Other objects of this invention are to provide means whereby theconcrete can be tamped in conjunction with the operation for filling themold with concrete.

Another object of this invention is to provide a means for locking theparts securely in position when the same is ready for the variousoperations, that take place in it.

A further object of this invention is to arrange the machine so that itcan be cheaply manufactured, and all its parts readily accessible to theoperator that operates it.

Another object of this invention is to have the parts removable, so thatthey can be readily inspected and repaired whenever the same isnecessary.

Other objects of this invention will become apparent as it is more fullyset forth.

Although there are many machines on the market for the manufacture ofconcrete blocks, and the like, they are more or less obj ectionable,because of the complexity of their parts, and the many differentoperations, that are required in them to bring about the desiredproduct. In most cases the making of concrete blocks requires the use ofseveral devices, which are independent of one another, and thereby causea lot of labor and expense which would be avoided by the cooperation ofthese various devices in a single machine.

This invention brings the operation of filling, tamping, and molding,and other incidental operations into one machine, and thereby makes itpossible to spend less labor in manufacturing concrete blocks, and atthe same time, this machine does not involve a relatively great expenseto manufacture it.

In the accompanying drawings which illustrate by way of example anembodiment of this invention; Figure 1 represents a view in elevation,partly in section of a concrete machine embodying this invention; Fig. 2is an end elevation of Fig. 1. Fig. 3 is a detail of the mold box.

Similar reference characters refer to similar parts throughout thedrawings.

In the accompanying drawings which illustrate the construction of thisinvention crete machine which preferably consists of uprights 2 and basepieces 3, to which is hinged a frame-work member 4: that is suitablyarranged to hold and guide a tamping bar 5 and a filling box 6 as isclearly shown in the drawings. The tamping bar has its lower portion 5hollowed out in order to permit the same to fit over a core 10. Theportion 5 is preferably removably held in place to the part 5 by boltsor other means, as shown in the drawings.

Secured to the bottom member 3 of the frame-work 1 are a number ofvertical rods 7 on which is arranged to slide a base plate 8, that formsa base for the concrete mold 9 disposed above it, and around the corepiece 10 when the device is arranged to make a hollow tile.

The filling box 6 is provided on this upper portion with a table 11 thathas a guiding slide 12 mounted on it, in order to guide the concreteinto said box, which has its sides 11 arranged to permit the concrete toflow therethrough into its interior. This box is normally disposed underthe tamping bar so that the same can be readily inserted therein andtamp the concrete properly into the mold 9. The concrete tamper isprovided on its lower portion with a band 10 which is arranged toactuate in and to loosely fit within the sides of the mold.

Rigidly mounted on, and secured to the member 4 is a bin, or hopper 13that is arranged to store the concrete that is to be used in the machineand which has provided under it a carrier 14 that consists of a chain 15having cleats 16 secured to it so as to engage with the concrete andpull it over the sprocket 17 when a handle 18 thereon is actuated by theoperator. The concrete is thereby pulled to the front part of themachine and dropped on the sliding plate 12. A sprocket 19 is providedat the back portion of the machine for suitably supporting the carrierat that joint.

The mold box 9 is preferably split into halves that are hinged as shownin detail in Fig. 3. This hinge permits the box toloe opened when theconcrete therein is solid enough for removal from the same.

20 is a suitable locking device for holding the mold securely inposition when the same is in the machine and ready to receive theconcrete. The mold frame 9 is held securely in position by any suitablemeans.

Provided on the lower portion of the box 6 is a lever lock 21 that isarranged to engage with one of the uprights 7 and lock the member 6 inthe proper position, for the various parts secured to the same. y

In the construction shown in the drawings we mainly indicate therein aconcrete machine that is constructed of wood, but it is not desired tolimit this application to this particular form of construction, becauseit is advantageous to use other materials, particularly those ofmetallic nature, and which, in their design, acquire a somewhatdifferent form to that shown in the drawings.

In operation, the operator actuates the handle 18 of the carrier 14 andthereby causes the concrete from the hopper 13, to be collected betweenthe various cleats 16 that are provided on the chain 14:- The mortarfrom between these cleats falls down the sliding piece 12 as the chainis made to travel from the sprocket 17. At the same time, the operatoractuates the tamping member 5 which puts the material properly in placein the molding frame 9, and makes the same as compact as possible, whichis a desirable result in this style of molding. After suflicientmaterial is in the mold frame 9, the member 4 is unlocked by the liftingof the latch 21, that keeps it securely in the operating position, it isswung side-wise from the machine, so as to leave the mold frame 9 freeto be lifted upwardly off the piece 3. After the material has setsufficiently the base plate 8 is raised, being properly guided by therod 7 and the mold frame 9 with it, at the same time, the core 10, whichis preferably slightly tapered upwardly as shown in the drawings, leavesthe interior of the molded concrete with a desired hole in the same.

The plate and mold are then removed to a suitable location and thefastening means 20 are unlocked, and the molded block removed from themold box 9, which is then returned to the machine and reused Copies ofthis patent may be obtained for five cents each, byaddressing theWashington, D. 0.

again for making another block. After the mold box has been replaced inposition on the machine, the member 4 is swung back into place andlocked and the same operations are repeated as previously stated.

Obviously while there is shown but one form of construction in thisinvention, in the drawings, it is not desired to limit it in any way,otherwise than necessitated by the prior art, as many'mo-difications inthe'construction of this invention may be made without departing fromthe principles thereof.

Having thus described this invention it is claimed:

1. In a machine of the class described, the combination of a supportingframe, means carried by the supporting frame for supporting a mold, astationary guide frame for said mold, a swinging frame connected to thesupporting frame, a vertically arranged guide duct also carried by themovable frame, the guide duct being movable by the motion of the movableframe so that it may be arranged either above or to one side of themold, and means carried by said guide duct for locking the same inposition over the mold, said means also serving to lock the frameagainst swinging motion. g

2. In a machine of the class described, the combination of a supportingframe, means carried by the supporting frame for supporting a mold, astationary guide frame for said mold, a swinging frame connected to thesupporting frame, a vertically arranged guide duct also carried by themovable frame, the guide duct being movable by the motion of the movableframe so that itm'ay be arranged either above or to one side of themold, and a cam locking lever carried by said guide duct for engagementwith the upper edge of the mold guide frame, the locking lever beingadapted to secure the guide duct over the mold and also to preventrotational movement of the movable frame. In testimony whereof wehereunto affix our signatures in the presence of two witnesses.
